I-Nitinol wire yezokwelapha iyingxube ye-shape-memory ethole ukusetshenziswa kabanzi embonini yezokwelapha ngenxa yezakhiwo zayo eziyingqayizivele. I-Nitinol wire yenziwe ngenhlanganisela ye-nickel ne-titanium, eyenza i-superelastic material engakwazi ukugoba nokusonteka ngaphandle kokulahlekelwa ukuma kwayo.
Enye yezinzuzo eziyinhloko zocingo lwezokwelapha lwe-Nitinol yikhono layo lokukhumbula ukwakheka kwalo kwasekuqaleni. Uma ishisiswe ngaphezu kwezinga lokushisa elithile, intambo ye-Nitinol izobuyela esimweni sayo sasekuqaleni, noma ngabe igobile noma icindezelwe. Lokhu kuyenza ibe into efanelekile ukuthi isetshenziswe emishinini yezokwelapha njengama-stents, lapho ingacindezelwa khona ngesikhathi ishutheka bese inweba ifinyelele ekumeni kwayo kwasekuqaleni uma isikhona.
Ngaphezu kwamakhono ayo enkumbulo yokuma, ucingo lwezokwelapha lwe-Nitinol nalo luhambisana kakhulu nezinto eziphilayo. Lokhu kusho ukuthi akubangeli ukusabela okubi emzimbeni womuntu futhi kungasetshenziswa ngokuphepha ezinkambisweni zezokwelapha ngaphandle kwengozi yokwenqatshwa noma imiphumela emibi.
Intambo ye-Nitinol nayo inamandla kakhulu futhi ihlala isikhathi eside, iyenza ibe yinto efanelekile ukuthi isetshenziswe emishinini yezokwelapha edinga ukumelana nengcindezi ephezulu kanye nobunzima. Iyakwazi ukumelana nokugqwala futhi ingakwazi ukumelana namazinga okushisa aphezulu, okuyenza ifanelekele ukusetshenziswa ezinhlobonhlobo zezicelo zezokwelapha.
Sekukonke, ucingo lwezokwelapha lwe-Nitinol luyinto ebalulekile enikeza izakhiwo eziyingqayizivele eziyenza ilungele ukusetshenziswa kumishini yezokwelapha. Amakhono ayo enkumbulo yomumo, i-biocompatibility, amandla, nokuqina ayenza ibe yinto eguquguqukayo engasetshenziswa ezinhlobonhlobo zezinhlelo zezokwelapha, kusukela kuma-stents nama-catheter kuya kwezinsimbi zokuhlinza nezinsimbi zokuqinisa amazinyo.
